T0 all whom t may concern:

Be it known that l, OSCAR J. GLM, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful lin-h provenients in Disk-Feeding levices, oi which the following is a specification.

My invention relates to improvements in machines for feeding and fastening disks of paper or other suitable material to envelops or sheets of paper, or other material, by means of eyelets, and the primary object of the invention is to provide means for rapidly and automatically feeding washershapcd disks beneath a reciprocating plunger and above an upsetting pin or horn, and simultaneously feeding an cyelet beneaththe plunger and above the disk, the

" parts being so arranged that the downward movement of the plunger forces the cyelet through the disk and upsets its lower end, thereby fastening the disk to the desired sheet, and the upward movement of the plunger feeds another disk into position to be secured by an eyelet at the next down ward movement of the plunger.

A further object of my invention is to avoid the paper punching operation and make a material saving in the cost of putting the eyelets and disks on the paper.

In the accompanying drawings forming part of this specification, Figure 1 is a side elevation of the eyel'et fastening machine with my invention applied thereto, showing the machine in its normal position, Fig. 2 is, a. similar view, showing the plunger depressed in the operation ot fasteningthc efelet and disinllig. 3 is a detail View, showing the receptacle in which the disks are placed and its position with respect to the' eyclet feed, Fig. l is a detail View showing the connection between the plunger' .and the disk feeding mechanism, Fig. 5 is a front view of the attachment, Fig. G is a. horizontal sectional view, showing the connection of the attachment to the machine l ,is a sectional view on the line ing pin 5 and normally held in its raised position by springs 6. A lever 7 is pivoted at 8 on the head of the machine and has a roller bearing 9 on an arm 10 that is also pivoted on the head 2 and adapted to bear on the plunger to depress the same when the lever 7 is drawn down by the treadle, not shown, that is attached to the bar 11.

12 isa hopper containing the eyelets fed to the work through a way 13.

The mechanism so far described forms a part of the machine to which l make no claim in this application.

1st is a tube or barrel, secured by suitable means to the head 2 and inclined slightly and provided with a plate l5 at its lower end. The disk used in this machine is usually of paper, having a central orifice and conforming to the shapepf an ordinary washer, the centralY opening being of suitable size to receivethe eyelet 17, such as is usually employed for fastening the disk to an envelop for the purpose of securing the l'lap of the envelop by means of a string wrapped around vthe eyelet under the disk. A reciprocatinor @feed plate 18 is mounted on the underside of the plate l5 and has a depression 19 therein of sutlicient depth to receive one of the disks, and is adapted to push the disks, one at a time, from beneath the pile into a position, (shown plainly in Fig. 3), directly beneath an eyelet in the eyelet way land in the path of the plunger. Beneath the plunger and the eyelet way is an anvilz2 having a pin 3 mounted thereon in the path of the plunger. This pin operates in coperation with its enlarged base to upset the lower end of the eyelet as the plunger descends.

Any suitable mechanism may be employed for reciprocating the feed plate 18 at predetermined intervals, but l prefer to provide an arm 20 attached to a plate '21.

that is pivoted at Q2 on a standard which projects upwardly from the disk receptacle. rl`he plate 21 has a cam edge Q3. A collar 2l is mounted on the plunger and a 1holt passes through this collar and suphat is aderted ,to receive l a. vcd

7.o on said inuit carries an anti-friction roller 30 that is adapted to contact with the cam edge when the plunger' has been depressed to 'a certain point. The normal position of the feed plate is as shown in Fig. 3, with a disk in the path of the plunger', and the plunger descends to a point where it engages and holds the disk before the anti-friction roller contacts with the edge 22?' to withdraw the feed plate. lV hen this contact takes place, the feed plate is retracted, leaving the disk, and withdrawn to a point where the next disk will drop into the depression in the feed plate and be carried forward on the return stroke of the feed plate. The arm 28 is provided with a slot 3l to receive the pin 32A mounted in the plate 2l, said slot allowing the arm 2S to slide toward saidl pin during the down stroke of the plunger, and on the up stroke the pin will contact with the end of the slot and swing the plate 21 inwardly to actuate the feed plate and project a disk Linto the path of the plunger. In case a disk should become jammed in the feed way, the spring 29 will yield and prevent breakage of thev connections between the plunger and the plate.

In ease the machine is operated at ahigh speed, a disk might be projected with suffi-A cient foree to ily out of the depression. I therefore prefer to provide retarding pins 33 which lbear onv the edge of the disk and hold it 'in placein the Way. I also prefer to provide stop pins 34 in the underside of the eyelet way in the path ofl the disks. to prevent the disks from being projected beyond the point where they will be engaged.

by the eyelet and the plunger.

ln the operation ofthe machine, theeyelets and disks will be automatically fed into the path of the. plunger, and :the operator, instead of first punching a hole in the body of the envelop, as usually required, Will insert the work between the plunger and the pin 3 and the descent of the plunger Will punch a hole through the paper and secure the disk thereto with one operation.

l have shown the disk feeding mechanism operated through the movement of the plunger itself, but do not Wish to confine myself toithis method of operation, as the feed plate may be connected to some other movying part of the rachine and still be Within the scope of my invention.

I claim as my invention. y
